What brand do you guys prefer if you are not custom building one? All of mine..as far as I know, have been "All Glass Aquarium" and they are doing me just fine. Let's get something started on your preferences.
Aqueon. my 150 was a custom order made with black silicone and it is awesome.
I compared the Aqueon 150 with the Perfecto 150 and the difference was suprising- the Aqeon had thickier silicone seals, thicker glass and two cross braces as opposed to only one in the Perfecto tank..of course, I went with that brand no questions asked.
we also have a local tank manufacturer called Miracles Aquariums that makes amazing tanks too. it is quite popular with the saltwater folks in the states - lots of talk about them over on Reefcentral.
